Abstract

A system for detecting electronic components includes a light-source device, a photography device, an adjustment device, and an image-processing device. The light-source device generates a light to illuminate at least one pin of a first electronic component at different rotation angles. The photography device senses the light and generates first and second images corresponding to the pin of the first electronic component at different rotation angles. The adjustment device adjusts the photography device and the light-source device to a first height and a second height, wherein the first images correspond to the first height and the second images correspond to the second height. The image-processing device calculates first feature information of the pin of the first electronic component according the first and second images, and analyzes the state of the pin of the first electronic component according to the first feature information.
